Why don’t strollers have large batteries?

Why doesn't the stroller have a large battery? ——In-depth analysis of safety and design

In recent years, electric strollers have become a popular product in the children's toy market, but many parents have discovered that most strollers on the market are not equipped with large-capacity batteries. This phenomenon has sparked widespread discussion. This article will analyze the reasons behind this for you from the perspectives of safety, regulatory restrictions, children's needs, etc., combined with hot topic data from the entire network in the past 10 days.

1. Statistics of hot topics across the entire network (last 10 days)

2. Safety is the primary consideration

1.Risk of battery overheating: Large-capacity batteries are more likely to generate high temperatures during charging and discharging. Children's lack of awareness of dangers may cause burns or fire accidents.

2.weight balance problem: Data shows that for every 1kg increase in battery weight, the probability of a stroller overturning increases by 23%. The weight of standard stroller batteries is usually controlled within 1.5kg.

3. Regulations and Standard Restrictions

1.international standards: EN71-1 EU Toy Safety Directive clearly stipulates that the maximum speed of strollers must not exceed 6km/h. Large-capacity batteries may cause overspeeding.

2.Domestic requirements: GB6675-2014 stipulates that the power of stroller motors shall not exceed 240W and the battery voltage shall be limited to less than 24V.

3.age appropriate: The battery capacity of products used by children aged 3-8 years old is essentially different from that of adult electric vehicles.

4. The particularity of children’s use scenarios

1.Length of use: Children's attention span is short. Market research shows that the average single use time is 47 minutes. There is no need for a large battery life.

2.Charging management: Parents prefer charging at night, and small-capacity batteries that are used intermittently during the day fully meet their needs.

3.motor development: Pediatric experts suggest that electric strollers should assist rather than replace children's sports. Long battery life is detrimental to health.

5. Technical solutions and development trends

1.Fast charging technology: New 30-minute fast-charging batteries have begun to be used in high-end stroller products.

2.Increased energy density: Graphene battery laboratory data shows that the capacity can be increased by 40% under the same volume in the future.

3.Intelligent speed limit:GPS geofencing technology automatically limits vehicle speed in specific areas.

6. Buying suggestions for parents

1. Look for the CCC certification mark and reject products with three no’s.

2. Prefer removable battery design for easy replacement and maintenance.

3. Pay attention to the battery cycle life indicator. A high-quality battery should ensure that the capacity is no less than 80% after 300 cycles.

4. Do not modify the circuit system by yourself, as this will invalidate the product warranty and increase the risk.

From the above analysis, it can be seen that not connecting a large battery to a stroller is a reasonable design that comprehensively considers safety, regulations and children's characteristics. With the advancement of technology, better battery life performance may be achieved in the future while ensuring safety, but at this stage, parents should fully understand the original intention of the design and choose appropriate products for their children.
